Impact of COVID-19 on dental education in the United States.

Dental institutions in the United States are reeling from the consequences of the novel SARS-CoV2 coronavirus, the causative agent of CODIV-19. As oral health care providers, we have been trained on prevention of aerosol transmissible diseases, but we are still grappling with many unknown factors regarding COVID-19. While the Centers for Disease Control and Prevention (CDC), American Dental Association (ADA), and local state agencies are releasing updates on guidelines for dentists and patients, no official information exists for dental institutions on how to effectively follow the recommended guidelines including "shelter in place" with social distancing to protect students, faculty, staff, and patients, and still ensure continuity of dental education.

Understanding root resorption with diagnostic imaging.

This article presents the clinical, radiographic and histopathologic features of various types of tooth root resorption. Tooth resorption may occur in a tooth internally or externally with distinctively different treatment approaches for each type of resorption. Given that proper diagnosis of the type of resorption is important, the use of cone beam computed tomography (CBCT) and conventional 2-D intraoral images in evaluation of resorptive lesions is discussed.

Restoring erosion associated with gastroesophageal reflux using direct resins: case report.

Gastroesophageal reflux disease (GERD) is a condition where stomach acids are chronically regurgitated into the esophagus and oral cavity, resulting in pathology, such as esophagitis, varices or ulcers. Continual exposure of the teeth to these acids can also cause severe dental erosion. This condition frequently is asymptomatic, and the only evident sign may be the irreversible erosion of tooth structure.
